l To'aZZ whom it may concern.'

- Be it known that l, Ro'sALIA H. HEINZE, a citizen ofthe United States, residing at Kellogg, the county of Wabasha and State of Minnesota, have invented anew and. useful l Cultivator, of which the following is a speciground ication.

This invention relates to one-horse cultivators, and has for its princi al object to provide a newer, quicker an less expensive form of implement for working more particularly in'strawberry iields on a larger scale than at present and to a greater and better advantage. 1

A 'further object of this invention is to combine in one implement devices for disking, cultivating and dragging or harrowing at the same time, such operations being of reater beneiit to strawberry plants than w en` these operations are performed independently, as less disturbance is caused to the plants anda greater amount of work is .performed with less labor and time.

Another object of the invention relates to the construction of the frame whereby the implement is made-to travel in one row or in two rows, straddling the plants, and when so working cuts the runners from the plants on both -sides of the rows at the same time.

A still further object relates to certain adjustments for increasing and decreasing the pressure on the drags or harrows, and the lateral spread of the harrow frame. L With these and other objects in view, the invention comprises the' various novel features of construction and combination and arrangement of parts, which will be hereinafter more fully described and pointed out particularly in the appendedclaims.

In the accompanying drawings-Figure 1' is a side elevation of the harrow. Fig. 2l is a planview of the same opened out. Figs; 3 land 4 are views of certain vdetails of the invention. p

Corresponding parts in the several figures are indicatedthroughout by similar characters ofreference.

The central or main beam of the cultivator indicated by 5 is preferably made of a length of iianged metal to which the various arts of the cultivator are directly or indirect 'y attached. On the forward end of the beam 5 curved is an arc-shaped coupling 6 having a bolted end adjustabl-y fastened to said coupling 6 by a bolt Q passing through the slot 7. The forward en of the beam 8 carries a swingletree 1 O.

Tntermediately secured to the short beam 8 between the head 6 and the swingletree 10 is a bracket 1l vconnected to the beam 8 by a vertical pivot bolt 12. When the cultivator is set, asin Fig. 2, to straddle the row of vplants to be cultivated, the bolt 9 is loosened and the short beam 8 turned-to one side or the other, as in dotted lines,'in order to let the horse or other animal drawing the cultivator walk' `between the rows of' plants. Pivoted to the ends of the bracket are two beams 13 and 14 extending rearwardly one oneach side of the central beam 5 each of which carries a pair of disks 15, a gang of Conveniently attached to t e main beaml 5 are handles 18 of the usual form.

The disks 15 are at the forward endv ofthe c'ultivator and are each mounted'on an arm 15a fastened in pairs to clip plates 15b, each clip plate having a movable connection with f one of the side beams 13 Aand 14. This connection is shown in the drawi as 'comprising the plate 15b below the side eam, a plate 18 above the same, and bolts 19 extending through said. plates. By loosening these bolts, the disks maybe moved forward or backward on their supporting beams To roperly operate upon the ground, these disks are not set inline with the direction of movement of the cultivatorbut have their rear sides inclined outwardly, as shown in Fig. 2, so that when cutting ground and runners of the plants theywillxbe forced away from the row. In p ace of the disks 15, knives or rolling colters may be used, but as these are common in the art, they have not been illustrated.

Behind the disks are the. cultivating shovels 16 there being three attached to each side beam 13 by means of a plate 16a carrying the shovels and extending transversely of the beam on its under side, and a clamping late 20 on the upper side ofthe beam an bolts 21 for fastening the two plates together. This arrangement ermits the cultivators to move on the sidb beams in the ,same manner as the `disks move. The innermost cuitivator shovel on each side of the main beam 5 follows directly behind the inner disk. on the same side and tends to break up the clods or lumps of dirt thrown outby l said Still further to the rear aref theA cultivators 16 and a draf or harrow 17.

or harrows 17 adjustably attached to the side beams 13 and 14. 4This adjustment permits .of forward and rearward movement similarto that of the disks andcultivator,

j butbesides the forward and rearward moves ment,ofthe harrows," they have a' vertical movement, the object ofjwhichis .to force thrmi, more" or less, into the ground to pull verite it as deep as the'nature-'of the, plants der cultivation calls for. rlhis is Vaccomp'i...ied by a cross shaft 22extending from he side beam 13 tothe opposite beam 14 turningin bearings 23 thereon and having an ai-m24' projecting forwardly on each sidewith a-downwardly extending -link 26'con vnected to and vbearing on the harrow frame.

a bearing 27 fastened; tothe main beam 5'l carriesa'toothed arc28 to engage with a .locking device of any ordinary form on a'` hand lever- 29 fixed to the shaft 22 where it passes through the bearing 27. As the lever moves to and fro, the harrows or drags are raised and lowered, and -when'the roper depth has been reached, they are held ocked b'yfthe toothed arc engaging the locking device onthe hand lever 29.

shown in Fig. 2, the invention is represented as 'spread to operate as a straddle-row cultivator. If it'be esired to narrow or reduce the width of the implement' so that it `may be used between rows ofplants, the

mechanism now about to be described is used for that purpose. Pivotedto each side beam` 13 and 14 are two jointed bars 30 and l is accomplished by means of a handlever 32 extreme rear ,end' of the central beam 5.

pivoted to the central beam 5, one arm of which extends below said beam and is 'connected by links 33 and 34 to rods 35 and 36,

res ectively, pivoted to the jointed bars 30 an 31. The rods 35 and 36 may be con- UAected to the inner or outer sections of both bars 30 and 31,- or to one inner section and ione outer section, as shown. The hand lever has a locking bolt of usual type for engaging a taothe'd sector 37".

la/addition to the 'several cultivator devices hereinabove described, there is further providedv a combination vcultivator comprising a central shovel and side harrow lteeth attached to the same lbeam from lwhich ya standard rises and is bolted to the This peculiar -cultivating implement is represented in Fig. 3 where a cultivator shovel and a vseries of `.harrowf teeth are shown attached to a beam 38,'fromthe center of' which a standard 3 9 rises to be attached, as'
